Conferència impartida a la sala de juntes de l'FNB pel professor Peter Bueken de l'Antwerp Maritime Academy (Bèlgica). "Chemical tankers often transport large amounts of toxic or dangerous products such as benzene, toluene, ... Exposure to these products presents a health hazard for the crew members of such ships, and precautions are necessary to protect them. During certain operations (loading and unloading, ventilating and cleaning tanks), vapours of these products are sometimes released into the air around the ship.
At Antwerp Maritime Academy, Capt. Werner Jacobs (one of the staff members) is currently investigating (as part of a PhD project) the behaviour of these vapours under different conditions (wind speeds,
directions, outlet velocities). One of the aims of his study is to investigate the flow and concentration of these vapours around the ship's superstructure by means of wind tunnel experiments. "Particle Image Velocimetry" (PIV) is a technique which allows the visualization of the flow of particles through a fluid (e.g. the air in a wind tunnel). This is typically done by "seeding" the fluid with visible "tracer particles" and analyzing the differences between two or more images of the fluid, taken with short time intervals. The relative movement of the particles from one image to the other allows one to determine the flow of the surrounding fluid. We are currently investigating whether PIV can be used to analyze the images obtained from the wind tunnel experiments.

The aim of this talk is to briefly describe the wind tunnel setup used in this experiment and to show some results of the experiments performed. Next, we will look at the ideas and mathematical techniques underlying the PIV-approach to the analysis of fluid flows and present some preliminary results of this research work in progress."

Gemma Agustí is fond of something Jules Verne once said: science is made up of a series of mistakes that lead little by little to the truth. ‘It’s true! A bad result shouldn’t discourage you or make you lose hope.’ She insists, ‘Research is addictive. Every time you obtain a positive result, you want to do it some more!’

Agustí’s research focuses on pathogenic microorganisms found in wet environments such as swimming pools and accumulated rainwater that cause spontaneous abortions, or miscarriages. She received a start-up grant from the UPC and is currently studying these pathogens and identifying sources of infection.

The bacterium Waddlia chondrophila is believed to cause abortions in bovines and has, in recent years, been directly linked to spontaneous abortions in women in the first trimester of pregnancy. The ecology, route of infection and prevalence in the environment of this pathogen are all unknown and, thus, so is the route of transmission.

A Gemma le gusta mucho una frase de Jules Verne que dice: la ciencia se compone de errores, que a su vez son pasos hacia la verdad. "Es totalmente cierto, un mal resultado no ha de desanimarte y hacerte perder la esperanza de continuar avanzando en tu investigación". Además, asegura, "la investigación engancha, ya que cuando obtienes resultados positivos tienes ganas de seguir avanzando...".

Su línea de investigación se centra en el estudio de microorganismos patógenos que generan abortos espontáneos. Estos patógenos se encuentran a menudo en recintos acuáticos como las piscinas, acumulaciones de agua de lluvia, etc. Ha recibido de la UPC una ayuda de iniciación a la investigación y, actualmente, su proyecto se encuentra en la fase de búsqueda e identificación de las fuentes de contagio de estos microorganismos. Waddlia chondrophila es una bacteria, considerada un patógeno causante de abortos en bovinos, y durante los últimos años se ha vinculado como causa directa de abortos idiopáticos, en mujeres embarazadas en el primer trimestre. De este patógeno, se desconoce la ecología, la ruta de infección y la prevalencia en el ambiente y, por lotanto, se desconoce su vía de transmisión.
